Notes

GENERAL INFO

Lui is a pronoun. It typically means "him" or "her" when used as an indirect object, or "he" / "him" when used as a stressed (disjunctive) pronoun.

USAGE

As an indirect object, lui replaces "à + person": "Je lui parle." (I talk to him/her). As a stressed pronoun, it emphasizes or follows prepositions: "C'est lui." (It's him). "Avec lui." (With him).

TRAPS

Lui refers to both masculine ("to him") and feminine ("to her") singular indirect objects, so context is crucial for understanding. Do not confuse it with direct object pronouns like "le" (him) or "la" (her).
